Evaluation of Apatite II™ for removal of copper and zinc from highway stormwater runoff : laboratory and field experiments

Creator:: Provolt, Justin J.
Abstract:: Current best management practices (BMPs) for stormwater treatment are not able to adequately remove heavy metals to levels which do not adversely affect aquatic life. Copper is commonly found in highway stormwater runoff, with the primary source being brake pad wear. Copper is of particular concern due to inhibitory effects...

The assessment of copper and zinc removal from highway stormwater runoff using Apatite II™

Creator:: Huang, Hsiao-Wen
Abstract:: Copper and zinc are heavy metals commonly present in highway stormwater runoff. Discharge of these metals to surface waters inhabited by sensitive aquatic species including threatened and endangered salmonids has necessitated the need for improved treatment techniques. Although copper is of the greater toxicological concern, zinc is often present at...

The role of zinc in the molecular and cellular events in the prostate

Creator:: Yan, Michelle
Abstract:: Zinc is an essential mineral that is integral to many proteins and transcription factors that regulate key cellular functions. The normal prostate accumulates high concentrations of zinc; however, malignant tissues have significantly lower zinc levels. This unique relationship between zinc and the prostate has sparked interest in the role of...

The function of zinc in the maintenance of DNA integrity in vivo

Creator:: Song, Yang
Abstract:: Approximately 12% of Americans do not consume the amount of zinc equal to the Estimated Average Requirement for zinc and could be at risk for marginal zinc deficiency. Zinc is an essential component of proteins in the defense against oxidative stress and DNA damage repair. Specifically in the prostate, zinc...

Assessing the effectiveness and environmental impacts of using natural flocculants to manage turbidity

Creator:: Kegley, Laura J.
Abstract:: The objective of this research was to determine the feasibility of using chitosan as a natural flocculant to control turbidity during in-stream construction work. A series of field tests in Oak Creek, Corvallis, OR were conducted in order to test the effectiveness for turbidity control and the environmental impacts of...

Ecological Consequences of Marine Debris: Understanding Large-Scale Species Transport on Tsunami Debris and Research Priorities in Oregon

Creator:: Gillman, Reva A.
Abstract:: The release of marine debris into the oceans and seas is a global issue of growing concern. These materials are harmful to marine environments and can also transport non-native species to novel habitats. Non-native species floating on marine litter is one of the lesser known impacts associated with marine debris....

Factors influencing residual stand damage levels due to cable thinning of coniferous stands in western Oregon

Creator:: Caccavano, Michael P.
Abstract:: The purpose of this study was to determine the significant variables influencing the damage levels sustained by the residual stand after skyline thinning of coniferous stands. Damage levels were measured in ten study areas in western Oregon that had received their first commercial thinning. For this post-logging study, 38 units...

The effect of ration formulation on the subsequent generation of volatile gases and odors from bovine waste

Creator:: Kellems, Richard O.
Abstract:: The objective of this study was to determine the effect that ration formulation has on volatilization of gases and offensiveness of the odor associated with the wastes produced from Holstein replacement heifers. Six separate experiments were conducted to study the relationships between different variables on the release of hydrogen sulfide,...

The agronomic, environmental, and economic implications of the introduction of terbacil for weed control in Oregon commercial peppermint operations

Creator:: Harris, James O.
Abstract:: The use of terbacil for weed control was adapted by a high percentage of Oregon peppermint growers soon after its introduction in 1967. To help clarify some of the implications of terbacil usage, three studies were undertaken to collect information concerning (a) the movement and build-up of terbacil in various...

Evaluating dairy waste management systems ̓influence on fecal coliform concentration in runoff

Creator:: Grismer, Mark Edward
Abstract:: This paper examines the environmental factors influencing the die-off and transport of fecal coliform bacteria present in wastes applied to the land surface. These factors are examined specifically for dairy waste management systems and the net effect each system has on runoff water quality. A model is developed that considers...

An analysis of two adjacent agricultural watersheds in west central Oregon

Creator:: Schoeneberger, Philip James
Abstract:: Two small adjacent watersheds on the west-central edge of the Willamette Valley of western Oregon were studied. Information was gathered on existing conditions to determine the suitability of the two watersheds for a paired-watershed study design. A soil survey was conducted using slightly modified soil series previously established for the...

Diclofop in runoff from agricultural watersheds in a high winter rainfall zone

Creator:: Hickman, John Spencer
Abstract:: Diclofop-methyl [me yl 2-(4-(2,4-dichlorophenoxy) phenoxy) propanoate] hydrolysis, degradation, and leaching were studied in field and laboratory experiments. Greater than 75% of the applied diclofop-methyl hydrolyzed to diclofop in 2 days at 4°C, the prevailing soil temperature during western Oregon winters. Degradation beyond the diclofop molecule, also an active herbicide, was...

Deposition and persistence of polynuclear aromatic hydrocarbons after slash burning clear-cut sites in Oregon

Creator:: Sullivan, Timothy Joseph
Abstract:: Research has been completed which identifies qualitatively and quantitatively the deposition, persistence and fate of polynuclear aromatic hydrocarbons (PNAH) on burned clear-cut sites in Oregon. Eight PNAH were identified and quantified in post-burn litter samples taken from four slash-burned sites. Deposition of lower molecular weight, 3-4 ring compounds was considerably...
